Have you ever noticed that almost every zipper has the letters YKK on it? The YKK stands for Yoshida Kogyo Kabushikikaisha. In 1934 Tadao Yoshida founded YKK, which is now the worlds largest zipper manufacturer, making about 90% of all zippers in over 206 facilities in 52 countries. YKK not only makes zippers and fasteners for clothes, cars, bags, and just about anything that needs to be closed, it also make the machines that make the zippers.
